Vedclass · Answer

$\left.2 N _2 O _5 g \right) \rightarrow 4 NO _{2( g )}+ O _2( g )$

$\Rightarrow k =\frac{\left[ NO _2\right]^4\left[ O _2\right]}{\left[ N _2 O _5\right]^2} \rightarrow(1)$

$N _2 O _{5( g )} \longrightarrow 2 NO _{2( g )}+1 / 2 O _2( g )$

$\Rightarrow k ^{\prime}=\frac{\left[ NO _2\right]^2\left[ O _2\right]^{1 / 2}}{\left[ N _2 O _5\right]}$

$\Rightarrow\left[ N _2 O _5\right]=\frac{\left[ NO _2\right]^2\left[ O _2\right]^{1 / 2}}{ k ^{\prime}} \rightarrow(2)$

$(2)$ in $(1)$ $\Rightarrow k =\frac{\left[ NO _2\right]^4\left[ O _2\right]}{\frac{\left[ NO _2\right]^4\left[ O _2\right]}{ k ^{\prime 2}}}= k ^2$

$\Rightarrow k\, >\, k$
